These are my boys! The red double tail is my fiance's, his name is Lieutenant Dan. The crown tail (named Sprinkles) and the yellow half moon (named Freckles) are mine. The yellow half moon I watched for like three weeks in petco before he started to get sickly looking and I brought him home. Mine share a 10 gallon divided and my fiance's fish has his own 5 gallon :)
